This document discusses social networks and their role in education. It outlines three key parts of social networks: creating a profile, forming connections with other users, and viewing connections. Social networks allow users to make visible social connections, unlike other forms of communication. Research shows social networks like Facebook can foster both strong and weak social ties. They also help young people, especially those from low-income families, build peer connections based on interests rather than geography and access influential information and relationships. While some see online communication as inferior, research finds it can be just as friendly, social, and intimate as face-to-face interactions.
